Moulsess-Invisible computer mouse


Mouseless is an invisible computer mouse that provides the familiarity of interaction of a physical mouse without actually needing a real hardware mouse

As the computer mouse has remained largely unchanged over the last decades, have become increasingly proficient at operating the two-button mouse. Recently, various multitouch and gestural interaction technologies have been explored as means to implement alternative methods to interact with a computer. Despite these advances in computing hardware technologies, the two-button computer mouse has remained the predominant means to interact with a computer. The Mouseless invention removes the requirement of having a physical mouse altogether but still provides the intuitive interaction of a physical mouse that we are familiar with. Mouseless consists of an Infrared (IR) laser beam (with line cap) and an Infrared camera. Both IR laser and IR camera are embedded in the computer. The laser beam module is modified with a line cap and placed such that it creates a plane of IR laser just above the surface the computer sits on. The user cups their hand, as if a physical mouse was present underneath, and the laser beam lights up the hand which is in contact with the surface. The IR camera detects those bright IR blobs using computer vision. The change in the position and arrangements of these blobs are interpreted as mouse cursor movement and mouse clicks. As the user moves their hand the cursor on screen moves accordingly. When the user taps their index finger, the size of the blob changes and the camera recognizes the intended mouse click.



As Pranavmistry improve our computer vision algorithms, an extensive library of gestures could be implemented in addition to mouse movement and mouse clicks. Typical multitouch gestures, such as zooming in and out, as well as novel gestures, such as balling one’s fist are all possible. In addition, the use of multiple laser beams would allow for recognition of a wider range of free hand motions, enabling novel gestures that the hardware mouse cannot support.



Pranavmistry implemented a fully functional working prototype system of 'Mouseless' that costs approximate $20 to build.

Custom Domain for Your Blogger Blog



Blogger is a best blog port to publish your blog it is the fastest and easiest way to use all of Blogger's great features. (And for free, no less!) If you don't care to have blogspot.com in your blog's address, though, you can get a domain of your own. Blogger will continue to host all your content as before, but it will be displayed at your new address. (Unlike FTP publishing, which requires you to buy both a domain name and a hosting service.)

Choose and Register Your Domain
The first thing you'll need to do is to choose a domain name, like example.com and register it. You can register domain names from any of a number of different registrars, and you can use .com, .org, .net or any other valid addresses. Remember: you only need to get the domain name; you don't have to pay extra for hosting service. The easiest way to register a domain is to buy your domain directly through Blogger. If you go this route, we'll automatically configure all of your relevant DNS settings and attach your new domain to your existing blog immediately.

Update the DNS Settings

DNS stands for Domain Name System, and a DNS server determines what site a given address takes you to. So far, you have a domain name but none of the servers on the internet know what to do with it yet. To take care of this, you need to do two things:

Create a CNAME record for your blog's address, which should be a subdomain of the form

www.example.com.
To create a CNAME record for your domain with the DNS, associating your domain with:

ghs.google.com.

The exact procedure for doing this varies depending on your domain registrar, but you can find instructions for many common registrars here. If yours isn't listed, or if you run into other difficulties, you can contact your registrar directly and they'll be able to help you out.
Create 'A' NAME records for your naked domain (blog.com)


Note: The following information applies to naked domains only!! If you're setting up a subdomain then this does NOT apply to you! :-)
Creating A records for your naked domain is important as it allows Google to redirect people who use in your naked domain name (blog.com) to your blog page (www.example.com). If you do not do this, visitors who leave off the www will see an error page.
There are four separate A records you will create, and can be done from the same control panel you accessed your CNAME records. Simply point your naked domain (example.com, without the 'www') to each of the following IP addresses:
216.239.32.21
216.239.34.21
216.239.36.21
216.239.38.21
Your DNS setup is now complete!

Update Your Blogger Settings
Almost done! At this point, you have a domain name, and the DNS servers know to direct people to Google when they want to see your blog. But Google hosts lots of blogs, so we have to make sure the right one is associated with this domain. You'll do this on the Settings Publishing tab for your blog in Blogger.


give your domain name and save then all the post and blog will redirect to custom domain.

If you're publishing on BlogSpot, you'll see a link near the top offering to switch you to a custom domain. Go ahead and click that link.
